Abstract

“Sugars,” also known as mono-, di-, and oligosaccharides, are included in the nonfiber carbohydrates. They are rapidly fermented in the rumen, yielding microbial cells, organic acids, gas, and microbial glycogen. Compared to starch, fermentation of sugars appears to yield more butyrate and …
